REMOVABLE COVERING FOR BOILERS! Specification of Letters Patent. Pate t d D 2-1 2 Application filed September 19, 1916, Serial No. 121,034. Renewed May 18, 1917. Serial No. 169,570.

To all whom it may concern.

Be it known that I, JAMES C. lVoRKM N, a citizen of the United States, and a resident'of Lakewood, county of Cuyahoga and State of Ohio, have invented a new and useful Im rovement in Removable Coverings for Boilers, of which the following is a specification, the principle .of the invention being herein explained and the best mode in which I have contemplated applying that necessary that such a covering be used ona portion of the boiler, although if it is desired the entire boiler may be covered with a'removable or sectional covering constructed in accordance with the principles of the present invention. To the accomplishment of the foregoing and related ends, said invention, then, consists, of the means hereinafter fully described andparticularly pointed out in the claim.

- The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing 2-- Figure 1 is a perspective view showing the outer end of a boiler provided with my improved covering; Fig. 2 is a bottom lan view of one of the removable sections; ig. 3 is a longitudinal section on the line 3-3, in Fig.- 2; Fig. 4 is a transverse section on the line 4-4. in Fig. 2, and Fig. 5 is a perspecti've view from below of a modified form of section.

In Fig. II have shown a boiler 1' of the usual horizontal type which is covered with asuitable jacket of refractory material, such as asbestos or fire-brick. It is desirable that the central portion ofthe end of the boiler Y and certain portions of the sides of the exposed part be accessible for inspection. Extendlng around the boiler are shown a number of lIOIl straps 2, disposed at equidistant intervals, thus forming panels or sections along the sides of the boiler. section is where the removable covering will preferably be used, since it is desirable at .tl'llS point to inspect the rivets in the head of the boiler.

The removable sections which are used for through which bolts 8 may be passed to hinge these sections together.-

The endmost' On the end of the boiler a similar construction is used except that each section is formed flat instead of being curved, and, if desired, the sections are held in place by reinforcing strips 11 which extend from the ends of the section to which they are attached.

A modified construction is shown in Fig. 5 where the framework 20 in which the refractory material is placed is provided across its bottom with a lacing 21 of wire,

which takes the place of the straps shown in the preceding figures, for the purpose of 1 holding the brick in place.

It is not, of course, new to employ a removable covering on a boiler, but the present invention is directed to the provision of a covering which shall be removable in conveniently handled sections, whichare, however, securely fastened together and main tained in place when once put in position.

Other modes of applying the principle of my invention maybe employed instead of the one explained, change being made as regards the mechanis herein disclosed, p ro- "-vided the means stated the following claim or the equivalent of such stated means such frame Work, said lacing being adapted be employed. to maintain such material in position. 10 I, thlerefore, particularly point out and Signed by me, this 14 day of Sept., 1916. distinct claim as m invention Y 5 In a li oiler covering a removable section JAMES WORIXMAN' comprising a shallow open frame Work, re- Attested by fractory material laid therein, and a wire N. M. SMITH, lacing extending across the open face of C. J. SAMUEL.
